* fix failing tests: expect s2 binutils to be installed on s3,
expect risc-v toolchain to be installed on s2 and s3.
* improve readability by adding assert_tool_installed and
assert_tool_not_installed functions, instead of using an optional
assertIn argument
* rename "RISC" to "RISCV_ELF" as ULP is arguably very much "R" as in
"RISC"!
Allow user to select specific ESP_TARGET while setting up ESD_IDF.
